In 1901 Claude Monet worked from the Savoy Hotel on the Strand for six months: A good choice for an artist in those days and presently for that matter and handy for his great works on the Thames. If I were to bump into him on one of my 4am rides ... (I have a bicycle: my major advantage over the great master) ... through Green Park, St.James Park and onto The Mall, Trafalgar Square and finally to his old and possibly present haunt on the Embankment between Waterloo Bridge and Parliament, I might suggest he move his Palette to the Hilton on Park Lane from which he would be able to view London, or half of it, from the bar on the 28th floor. Then when he'd absorbed the splendor in the Easterly direction, filled his canvas and emptied his glass, he could move through to the Restaurant and view the other half presently including the great modern work by Christo and Jeanne-Claude (The London Mastaba) floating in the middle of the Serpentine Lake in Hyde Park (see Hyde Park Galleries for details of the work).
I've lived and worked in the shadow of the Hilton on Park Lane for nearly 20 years and as a location to travel from and work in there is for me no better. If you are reading this from any of the rooms in the Hilton or better from the 28th Floor, find yourself a destination by looking out of the window: lets say Nelson's Column: its easy to pick out: then walk there making sure you stop for a coffee or a drink at somewhere you never thought you might go. (I'm going to recommend The Red Lion on Duke of York Street in St.James for this example). Take a camera, or your phone (its like a camera but you can also talk to it .... I'd go for the camera option, use the phone for what it was intended, to be a map and find the Red Lion).
The walk, I guarantee will rapidly turn itself into a journey for the journeys sake taking you out of your day and into another World. As Robert Louis Stevenson said ... 'The great affair is to move' and whilst moving if you find yourself lost, flag down a black cab and say 'take me to the Hilton', and they will reply ... 'On Park Lane', as everyone knows The Hilton.
ps: RL Stevenson stayed at The Craven Hotel on Craven St, just off the Strand when in London: I had to look that one up and I think it has gone: I will update from my bicycle.
